Is there any chance to upgrade the Windows Technical Preview to the latest preview version if using a Windows-To-Go USB drive created by WinToUSB? I'm asking because the default upgrade mechanism in Windows Technical Preview doesn't work for me. Instead, Windows keeps telling me that it can't install to a USB drive when I try to install the newest preview. If, however, you have to do a complete reinstall for every new version of the preview, the whole idea of installing the technical preview to a USB drive seems rather pointless to me.
